Third arrest made in fatal shooting of 7-year-old foster girl in DeKalb

Police have arrested a third suspect in connection with the fatal shooting of a 7-year-old foster girl who was struck in the head while sitting on the couch of her DeKalb County home. 

Dwayne Eric Allen, the 27-year-old uncle of two siblings previously charged in the April 12 shooting, was arrested Friday at an Atlanta business, DeKalb sheriff’s office spokeswoman Cynthia Williams said. 

According to warrants issued Thursday, Allen and his nephew, 21-year-old Antoine Allen, shot up an Ellenwood home on Satellite Boulevard with an AR-15 rifle.

Mariaisa Thomas, the 7-year-old inside the house at the time, was hit in the head, police said. She died of her injuries 10 days later.

“She was an innocent little girl just watching TV on the couch,” Thomas’ biological mother, Chanrica Boyd, previously told Channel 2 Action News. “It’s still unreal that this is my child that was shot up in this house due to something that wasn’t even involving her.”

Thomas was in the custody of the Division of Family and Children Services at the time of the shooting, authorities said. She had been in the foster home for only about two weeks.

Dwayne Allen, Antoine Allen and Keadesia Allen all remain held without bond at the DeKalb County Jail, records show.
